damage may occur.

6. Compress the brake lever repeatedly to ensure
correct positioning of the brake pads; then release.
NOTE: When new brake pads are installed, a bur-
nishing process is required. Drive the snowmobile
slowly and compress the brake lever repeatedly
until the pads just start to heat up; then allow them
to cool down. This process stabilizes the pad
material and extends the life of the pads.
REMOVING CALIPER
1. Slide a piece of flexible tubing over the ball of the
bleeder valve and direct the other end into a
container.
2. Open the bleeder valve and compress the brake
lever several times to drain the reservoir of fluid.
3. Remove the brake hose from the caliper. Use an
absorbent towel to collect any remaining brake
fluid.
! CAUTION
Brake fluid is highly corrosive. Do not spill brake
fluid on any surface of the snowmobile.
4. Remove the retaining pin securing the brake pads
to the caliper assembly; then remove the brake
